Using Light-sensitive Resistors (LDRs) for detecting occupancy of short blocks on a model railway

I needed something that would act as a detector on a double slip, which is a comparatively short length of track and ended up looking at light dependent resistors (LDRs), also known as photoresistors, or photocell resistors. The ESP32 LDR tutorial referenced in the video https://esp32io.com/tutorials/esp32-l... The LDR class and sample sketch used in the video https://github.com/Vintage80sModelRai... I've created a repo for all of my current live node sketches across the Arduinos, ESP32s and Galileos. All of them are written in the Arduino IDE. https://github.com/Vintage80sModelRai...
